ICStation TowerPro MG90S Metal Gear Servo

[@gokultamilarasan6466]

I want lever pulling mechanism 2kg, any video plz upload fast, I used servo method to pull, but hardware mechanical part failed, particularly lever not probably working, If any reliable method please tell

[@tsisapik]

You need to use a larger servo preferably metal gear with a metal servo arm if you are pulling 2 kg. These are 9gm servo size and would not be able to move anything near 2kg

Maybe the signal generator generates pulses from 1000us to 2000us that's why the MG90S isn't able to rotate 180° (I don't know for sure), perhaps, let's say... If the generator have generated 600us to 2400us the MG90S would be able to rotate 180° too... Thank you for the great video!!

[@tsisapik]

Truth be told, I would have no issue using MG90S servos on my models. Control surfaces are rarely set to move beyond 90 deg total end to end movement between the servo control arm and clevis settings. Nice to know that doing those white knuckle dives that the servo will not strip when you pull up. Dumb thumbs do not count. Regards.

Nice video, well done. I like the IC Station servo. The metal gears look very rugged. What brand was the servo with the full 180 degree deflection?

[@tsisapik]

The 180 deg servo is an analog Turnigy metal gear.

[@DroneRecipe]

hi, thanks for the video. i noticed that it said analog. I just bought a couple and they were advertised as being digital. any idea?

[@tsisapik]

They are analog servos otherwise they would be vibrating continuously..

[@ICStation2013]

Thanks for your awesome work!

Hi just wanted to know can it travel 180 degrees with use of arduino?

[@tsisapik]

Turn 180 deg with Arduino? Open Arduino 1.04 (other versions may have it as well). Go to File>Examples>Servo then upload any of the two sketches called "Knob" and "Sweep" ... . Read the code for connection instructions. "Knob" allows you to control the servo travel using a variable resistor. "Sweep" causes the servo to move back and forth 180 deg. Knowing this servo moves about 90 deg max, it might interpret 180 signal as 90 deg as well. It may have been physically designed to max out at 90 deg ... have not tried to increase that throw.

Can continuous servo be used for defined angle rotation like 60 degree and can you suggest some non continuous servos

[@tsisapik]

Can a continuous servo be used for defined angle ... probably not - the servo would need to receive a zero pulse to stop and these type of servos do not have the potentiometer for obvious reasons. The servo you need depends on the application. How much torque is required. What angular speed is required and most important - what is your price pain point.

[@jerrycaleb8035]

Torque above 2.3kgcm, angular speed no clue

[@jerrycaleb8035]

Torque above 2.3kgcm, angular speed no clue, budget is below 10dollars, should be available in india

[@tsisapik]

Then I suggest you google on-line stores for your servos from a store in Indian since I am in NJ USA.

If you are interested in really testing servos you might want to look into the YTV servo tester from York Electronics. It can really torture test them. Over the past several years I've been able to test and identify about 12-13 bad servos. Thankfully my testing with it helped to avoid any crashes or injuries. The nicest part of the YTV is it will do 60-degree sweeps (and overtravel) automatically and you can sweep at nine different speeds...from the slowest to the fastest imaginable...as well as manual settings. Centering is a snap to test for and it's able to test 4 servos all at the same time too! No, I don't work for them nor do I have any investments in them. I just think it's probably the best tester out there. www.york-electronics.com/index.htm

[@tsisapik]

Thanks for the heads up ... must be nice owning one of those gadgets ... alas one I do not have.

FAKE MG Servo. I don't know what is going on but Mines, I bought many, all of them have plastic gear between the motor and the metal gears :( making it useless as a metal geared servo and as prone to bake as a common plastic geared servo

[@tsisapik]

The servo housing are transparent and the metal gears can be seem even without opening the unit. If they are not metal gears then they should be returned and a complaint brought to the attention of the company you bought them from.

[@TheStickyBusiness]

tsisapik They are not that transparent anymore. I opened 14 because I needed to protect them for water landings with corrosion x. all of the 14 have a PLASTIC gear that links the motor to the metal gears :(

[@tsisapik]

I checked mine and it was all metal - so that's good. I believe you because I have seen "hybrid" servos - different brand though. My guess is that failure in the servos you got were on the plastic gear? The corrosion x could have weakened the plastic - but still not an excuse to have plastic. If I can ask ... 14 servos for water landings? What did you built an amphibian octopod? I have a 12 servo four legged puppy ... which is why I ask.

[@TheStickyBusiness]

tsisapik Te servos are brand new from banggood, two different batches bought in different times, the product is like corrosion x but is silicon base. I am preparing 3 airplane and a wing for water landings.

[@tsisapik]

Did you reach out to Banggood about your concern? They are usually responsive based on my experience but take a little time to get back to you ... however opening up the servos may have voided the warrantee. Fixed wings for water landing? Why MG servos? I understand MG's are more durable but are slightly heavier, slower and more expensive than regular servos.

[@an_what]

Don't let the tower pro metal great fool you its drive gear is plastic and it only has a half bearing at the top. Meaning if the MAIN PLASTIC DRIVE GEAR WEARS OUT you now have a useless metal gear servo

[@tsisapik]

No problems with current application of metal gear servos of this size ... they go to a robotic dog as replacement for the original servos that have stripped ... so far so good.
